Light variations of BD +14 341 can be resolved into three, apparently independent activities: (1) periodic variations with P=0.2658d and an amplitude of about 0.15 mag.; (2) quasi-periodic fluctuations with periods between 14 and 20 minutes and variable amplitude; and (3) small-scale, apparently irregular fluctuations ("flickering") with a time-scale of the order of 1 min. It is suggested that the star is a hot, subluminous close binary system.
